Benefits of technology
The solution enables efficient and automatic movement of the boom and bucket to a preset position, reducing operation time and enhancing manipulation efficiency, while minimizing manufacturing costs by eliminating the need for additional switches and electromagnetic systems.
Problems solved by technology
In addition, since the boom needs to be moved to a specific position only after the bucket is moved to the specific position thereof, an operation cannot be promptly performed.
Moreover, since an electromagnetic system needs to be used to maintain the bucket lever and the boom lever in a manipulated state, manufacturing costs of the construction machine are increased.

Embodiment Construction
[0025]Hereinafter, a position control apparatus and a position control method for a working machine of a construction machinery according to exemplary embodiments of the present disclosure will be described in detail.
[0026]Referring to FIG. 1, the present disclosure is adapted to control a position of a working tool 20 and 30, and the working tool 20 and 30 includes a boom 20 and a bucket 30. The boom 20 is installed in a body of the construction machine to be rotated upward and downward, and the bucket 30 is installed in the boom 20 to be rotated upward and downward. The construction machine moves to a location close to a conveying means in a posture of the boom 20 and the bucket 30 as illustrated by A of FIG. 1. Thereafter, the bucket 30 is dumped to state C via state B to load earth and sand contained in the bucket 30 on the conveying means. If the earth and sand in the bucket 30 is loaded on the conveying means and the bucket 30 becomes empty, the boom 20 and the bucket 30 are m...

Disclosed is a position control apparatus for a working machine of a construction machinery, including: a boom driving unit for driving a boom; a bucket driving unit for driving a bucket; a working tool manipulating part for generating a manipulation signal for driving the boom driving unit and the bucket driving unit; a kick-down switch for generating a kick-down signal for lowering a gear stage; and a controller for, if the kick-down signal is generated by the kick-down switch and the manipulation signal is generated by the working tool manipulating part, outputting a control signal to the boom driving unit and the bucket driving unit to move the boom and the bucket to a preset position.
Description
[0001]This application is a Section 371 National Stage Application of International Application No. PCT / KR2010 / 007811, filed Nov. 5, 2010 and published, not in English, as WO2011 / 074783 on Jun. 23, 2011.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to a construction machine such as a wheel loader, and more particularly, to a position control apparatus and a position control method for a working machine of a construction machinery for controlling a position of a working tool such as a boom or a bucket.BACKGROUND OF THE DISCLOSURE[0003]A construction machine such as a wheel loader is widely used in an operation of conveying and loading earth and sand. In more detail, the wheel loader raises a boom at a position close to a conveying means such as a truck and dumps a bucket containing earth and sand to load the earth and sand on the conveying means. Then, after the bucket is crowded to a horizontal position, a boom is lowered to fill earth and sand in the bucket. Such an o...
